MEMORY DEVICE WEAR LEVELING - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 17659897 Titled 'MEMORY DEVICE WEAR LEVELING'
Simplified Explanation
The abstract describes a method for managing the wear and tear of memory blocks in a memory device. The controller of the device monitors an endurance parameter associated with a group of memory blocks called the wear leveling pool. If the endurance parameter meets a certain threshold, the controller divides the memory blocks into two subsets. The first subset is used to store a portion of the data, while the second subset is used to store another portion of the data. This helps to evenly distribute the usage of memory blocks and prolong the overall lifespan of the memory device.
Original Abstract Submitted
A controller of a memory device may determine that an endurance parameter associated with a wear leveling pool of a memory of the memory device satisfies a threshold. The wear leveling pool includes a plurality of memory blocks of the memory. The controller may divide, based on determining that the endurance parameter satisfies the threshold, the plurality of memory blocks of the wear leveling pool into a first wear leveling pool subset that includes a first subset of the plurality of memory blocks and a second wear leveling pool subset that includes a second subset of the plurality of memory blocks. A first subset of a plurality of data partitions is stored in the first subset of the plurality of memory blocks, and a second subset of the plurality of data partitions is stored in the second subset of the plurality of memory blocks.
